* [svn-r13253] Updated all C and C++ style source code files with the THG ↵Albert Cheng2007-02-071-2/+3
| | | | | | | | | copyright notice. Tested platform: Kagiso only since it is only a comment block change. If it works in one machine, it should work in all, I hope. Still need to check the parallel build on copper.
* [svn-r13139] Fixed the MULTI problem (Bug #731) that corrupted the data. ↵Raymond Lu2007-01-121-4/+4
| | | | | | | The problem came from the EOA for the whole MULTI file. It's taken out because it's meaningless for MULTI file. Instead, each individual file has its EOA.

| | | | | | | | Take out separate memory type in the file for SOHM objects and create aliases for existing memory types for SOHM use. Tested on: FreeBSD/32 4.11 (sleipnir)
* [svn-r12902] Checkin of Shared Object Header Message work.James Laird2006-11-131-0/+1
| | | | | | | | | | | | This feature is still in progress; Shared Object Header Messages are not complete as a feature and are not thoroughly tested. There are still "TODO" comments in the code (comments with the word "JAMES" in them, so as not to be confused with other TODO comments). Hopefully this checkin will reduce the liklihood of conflicts as I finish implementing this feature. All current tests pass on juniper, copper (parallel), heping, kagiso, and mir.
* [svn-r12700] Alert:Quincey Koziol2006-10-021-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | File format is not stable, don't keep files produced! Description: First stage of checkins modifying the format of groups to support creation order. Implement "dense" storage for links in groups. Try to clarify some of the symbols for the H5L API. Add the H5Pset_latest_format() flag for FAPLs, to choose to use the newest file format options (including "dense" link storage in groups) Add the H5Pset_track_creation_order() flag for GCPLs, to enable creation order tracking in groups (although no index on creation order yet). Remove --enable-group-revision configure flag, as file format issues are now handled in a backwardly/forwardly compatible way. Clean up lots of compiler warnings and other minor formatting issues. Tested on: FreeBSD/32 4.11 (sleipnir) w/threadsafe Linux/32 2.4 (heping) w/FORTRAN & C++ Linux/64 2.4 (mir) w/enable-v1.6 compa Mac OSX/32 10.4.8 (amazon) AIX 5.3 (copper) w/parallel & FORTRAN
* [svn-r12692] Removed code that was used to support lazy allocation of file spaceJames Laird2006-09-281-1/+0
| | | | | | | since HDF5 no longer allocates file space lazily. Tested on mir; should be only a cleanup, since the code isn't called from anywhere.
* [svn-r12562] Description:Quincey Koziol2006-08-101-0/+4
| | | | | | | | | | | | Initial revision to add support for "huge" objects in the heap (which are actually stored directly in the file, but are tracked with v2 B-tree that is accessed through heap header). Testing: FreeBSD 4.11 (sleipnir) Linux/64 2.4 (mir) Linux/32 2.4 (heping) Mac OS X.4 (amazon)
* [svn-r12525] Description:Quincey Koziol2006-08-021-1/+1
| | | | | | | | | | | Refactored free space manager to use metadata cache for serialized free space sections. This speeds up the fractal heap test considerably... Tested: FreeBSD 4.11 (sleipnir) Linux 2.4/32 (chicago) Linux 2.4/64 (mir) Mac OS X (amazon)
* [svn-r12349] Purpose:Quincey Koziol2006-05-151-0/+12
| | | | | | | | | | | | | | | Code checkpoint Description: Checkpoint fractal heap improvements, as well as move the free space manager code that it's using into a separate package. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4/64 (mir) w/C++ & FORTRAN Linux 2.4/32 (heping) Solaris 2.9 (shanti) AIX 5.? (copper) w/FORTRAN & parallel
* [svn-r12004] Purpose:Quincey Koziol2006-03-041-2/+2
| | | | | | | | | | | | | | | | | New feature & code cleanup Description: Update fractal heap to be able to insert objects into a direct block hanging off the header. Extract "octal dump" code into separate routine so that both the local heaps & fractal heaps can use it. Other code cleanups & support to get this far. Platforms tested: FreeBSD 4.11 (sleipnir) Linux 2.4
* [svn-r11967] Purpose:Quincey Koziol2006-02-271-11/+14
| | | | | | | | | | | | | | | New feature Description: Check in initial "fractal heap" code, for supporting the group redesign. Also, remove some remnants of the segmented heap/block tracker/B+tree code which I didn't find during the last pass. Platforms tested: FreeBSD 4.11 (sleipnir) Mac OSX (amazon) Linux 2.4
* [svn-r11245] Purpose:Quincey Koziol2005-08-131-2/+2
| | | | | | | | | | | | | | | | | | | | Code cleanup Description: Trim trailing whitespace, which is making 'diff'ing the two branches difficult. Solution: Ran this script in each directory: foreach f (*.[ch] *.cpp) sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f end Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10628] Purpose:Quincey Koziol2005-04-181-2/+2
| | | | | | | | | | | Code cleanup Description: Clean up various warnings reported by the Windows team. Platforms tested: FreeBSD 4.11 (sleipnir) Too minor to require h5committest
* [svn-r10506] Purpose:Quincey Koziol2005-03-291-0/+8
| | | | | | | | | | | | New feature Description: Add first iteration of "segmented heap" code, which will be used to store links in groups in a more flexible way than the previous "local heap" mechanism. Platforms tested: FreeBSD 4.11 (sleipnir) w/parallel Solaris 2.9 (shanti)
* [svn-r10184] Purpose:Quincey Koziol2005-03-111-0/+5
| | | | | | | | | | | | | | | | | | | | New feature Description: Add new "block tracker" data structure to library, for tracking blocks of bytes in a file. Block trackers will be used to keep track of the blocks belonging to the soon-to-be-implemented "segmented heap" which is designed to replace the current local & global heaps (starting with the local heap). Block trackers will also keep track of the free space in the segmented heap and someday could be used to track the free space in the entire HDF5 file. They are implemented as a small header of information to cache the state of the blocks (max & min sizes of blocks tracked, etc.) and the records of the blocks themselves are stored in a v2 B-tree. Platforms tested: FreeBSD 4.11 (sleipnir) Solaris 2.9 (shanti) h5committest
* [svn-r8877] James Laird2004-07-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: Bug Fix Description: If an HDF5 file grows larger than its address space, it dies and is unable to write any data. This is more likely to happen since users are able to change the number of bytes used to store addresses in the file. Solution: HDF5 now throws an error instead of dying. In addition, it "reserves" address space for the local heap and for object headers (which do not allocate space immediately). This ensures that after the error occurs, there is enough address space left to flush the entire file to disk, so no data is lost. A more complete explanation is at /doc/html/TechNotes/ReservedFileSpace.html Platforms tested: sleipnir, copper (parallel), verbena, arabica, Windows (Visual Studio 7) Solution: Platforms tested: Misc. update:
* [svn-r7317] Purpose:Quincey Koziol2003-08-081-1/+1
| | | | | | | | | | | | | | | | Feature change & code cleanup Description: Changed fileno field in H5FD_t struct from 'unsigned long[2]' to just 'unsigned long'. Changed over code to handle the fileno change. Chased error API changes Platforms tested: h5committested
* [svn-r6500] Purpose:Bill Wendling2003-03-191-57/+87
| | | | | | | | | | | | New Feature Description: Added function pointers for the lock and unlock functions. Platforms tested: Linux, Modi4, Sol Misc. update:
* [svn-r6391] Purpose:Bill Wendling2003-02-101-3/+0
| | | | | | | | | | Fix Description: The extra field I put in this structure wasn't needed. Solution: Placed it in the file driver's structure instead. Platforms tested: Linux
* [svn-r6387] Purpose:Quincey Koziol2003-02-101-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: Metadata cache in parallel I/O can cause hangs in applications which perform independent I/O on chunked datasets, because the metadata cache can attempt to flush out dirty metadata from only a single process, instead of collectively from all processes. Solution: Pass a dataset transfer property list down from every API function which could possibly trigger metadata I/O. Then, split the metadata cache into two sets of entries to allow dirty metadata to be set aside when a hash table collision occurs during independent I/O. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} FreeBSD 4.7 (sleipnir) serial & parallel Misc. update: Updated release_docs/RELEASE
* [svn-r6381] Purpose:Bill Wendling2003-02-061-0/+3
| | | | | | | | | | | | | Field Addition Description: Added a File ID field to the H5FD_t structure so that, way deep down in the H5FD_* functions, I'll know what ID the SAP wants for this particular file. This is #ifdef'd out so that if you don't have FPHDF5 enabled, then it won't be there... Platforms tested: Linux
* [svn-r5951] Raymond Lu2002-09-301-0/+2
| | | | | | | | | | | Purpose: New API functions Description: Added API functions to return pointer to low-level file handle (H5Fget_vfd_handle and H5FDget_vfd_handle) and related property list setting functions(H5Pset_family_offset and H5Pset_multi_type). Platforms tested: Linux 2.2(eirene), Solaris 2.7(arabica), IRIX64 6.5(modi4)
* [svn-r5931] MuQun Yang2002-09-201-15/+15
| | | | | | | | | | | | Purpose: __DLL__ is a keyword in some platforms and __DLL__ is also defined as a macro for windows DLL applications. That causes problems. Description: Solution: Use H5_DLL*** to replace __DLL***__ at all header files. Change the macro defination at H5api_adpt.h. Platforms tested: linux2.2.18smp, irix64, solaris 2.7 and windows 2000
* [svn-r5550] Purpose:Quincey Koziol2002-06-071-3/+11
| | | | | | | | | | | | | | | | | Code Improvement Description: Split the metadata accumulator code into two parts: one for allowing writes of the accumulator buffer during reads (when the buffer is dirty and needs to be flushed to disk in order to hold the new metadata being read in) and another for only allowing writes of the buffer during writes. This allows the MPI-I/O VFL driver to use the metadata accumulator (but only during writes) and benefit from the reduced number of metadata I/O operations that it brings. Platforms tested: IRIX64 6.5 (modi4) w/parallel
* [svn-r5536] Purpose:Quincey Koziol2002-06-051-0/+11
| | | | | | | | | | | | | | | | | New feature. Description: Added a "small data" block allocation mechanism to the library, similar to the mechanism used for allocating metadata currently. See the RFC for more details: http://hdf.ncsa.uiuc.edu/RFC/SmallData/SmallData.html This reduces the number of I/O operations which hit the disk for my test program from 19 to 15 (i.e. from 393 to 15, overall). Platforms tested: Solaris 2.7 (arabica) w/FORTRAN and FreeBSD 4.5 (sleipnir) w/C++
* [svn-r5440] Purpose:Quincey Koziol2002-05-201-2/+2
| | | | | | | | | | | New feature Description: Add 'closing' parameter to H5FDflush and VFL "flush" functions, per http://hdf.ncsa.uiuc.edu/RFC/VFLFlush/VFLFlush.html Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5403] Purpose:Quincey Koziol2002-05-131-1/+1
| | | | | | | | | | Back out changes. Description: Back out changes to VFL 'flush' API function, pending review. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5393] Purpose:Quincey Koziol2002-05-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | New Feature Description: The VFL flush function is called immediately before a file is closed. This can cause duplicate syncronization actions to occur, if the VFL close function also performs them. Solution: Added 'closing' parameter to VFL 'flush' operation. This allows the VFL flush function to bypass operations that will be duplicated within the VFL close function. Additionally, use the 'closing' parameter to bypass calls to MPI_File_sync() when set. Since MPI_File_close() also syncronizes the file, this avoids the terrible performance hit taken when calling MPI_File_sync() as the file is closing. Platforms tested: IRIX64 6.5 (modi4)
* [svn-r5096] Purpose:Quincey Koziol2002-03-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix Description: The H5Gget_objinfo() function was not setting the 'fileno' field in the H5G_stat_t struct passed in. Solution: Added a "file serial number" to each file currently open in the library and put that in the 'fileno' field. If a file is opened twice (with H5Fopen) and the VFL driver detects that it is the same file (i.e. the two file structures have the same "shared file info" in the library's memory structures), they will have the same serial number. This serial number has two drawbacks: - If a VFL driver doesn't/can't detect that two calls to H5Fopen with the same file actually _are_ the same file, each will get a different serial number - If the same file is closed and re-opened, the serial number will be different. It is be possible to fix the second drawback for many VFL drivers, but it would be a lot of effort and probably isn't worth it until we've got a good reason to do it. Dunno if we'll ever be able to fix the first drawback... Platforms tested: FreeBSD 4.5 (sleipnir) VS: ----------------------------------------------------------------------
* [svn-r4696] Raymond Lu2001-12-111-17/+19
| | | | | | | | | | | | | | | | | Purpose: Modify H5Fclose behavior Description: The HDF5 actual file close behaves in several ways in terms of if there are still objects(dataset, group, datatype) opened in file. Solution: Added a new file access property, file close degree. It has four values, H5F_CLOSE_DEFAULT H5F_CLOSE_WEAK H5F_CLOSE_SEMI H5F_CLOSE_STRONG The way a file is closed is decided by these values. Platforms tested: IRIX64 6.5, SunOS 5.6, FreeBSD 4.4
* [svn-r4181] Purpose:Quincey Koziol2001-07-101-6/+6
| | | | | | | | | Bug Fix, Code Cleanup, Code Optimization, etc. Description: Fold in the hyperslab speedups, clean up compile warnings and change a few things from using 'unsigned' or 'hsize_t' to use 'size_t' instead. Platforms tested: FreeBSD 4.3 (hawkwind), Solaris 2.7 (arabica), Irix64 6.5 (modi4)
* [svn-r3881] Purpose:Albert Cheng2001-05-011-0/+2
| | | | | | | | | | | | Feature Description: The allocation by alignment (H5Pset_alignment) feature code somehow got dropped in some 1.3.x version. Solution: Re-implemented it with "new and improved" algorithm. It keeps track of "wasted" file-fragment in the free-list too. Platforms tested: modi4(parallel).
* [svn-r3781] Purpose:Bill Wendling2001-04-051-3/+4
| | | | | | | | | | | | | | | | | | Update Description: Changed #include <hdf_file.h> construct to #include "hdf_file.h" so that the GNU compiler can more easily pick up the dependencies which it places in the .depend and Dependencies files. Also regenerated the Dependencies to go along with this. Platforms tested: Linux
* [svn-r3008] Purpose:Quincey Koziol2000-11-281-0/+1
| | | | | | | | | | | | | | Code cleanup Description: Several places in the code were using -2 as a default value for various features. However, when a default value is returned from a function that is supposed to return negative on failure, it was causing confusion and extra work for users to check for the special value. Solution: Replaced hard-coded -2 values in the code with symbolic names, then changed symbolic names to 0 instead of -2. Platforms tested: FreeBSD 4.2 (hawkwind)
* [svn-r2722] Purpose:Quincey Koziol2000-10-241-2/+2
| | | | | | | | | | Feature symmetry Description: A while ago I needed to get the 'type' of data being accessed during writes to the VFL driver, so I put in code to get the information down there. Albert asked for the same information during reads, so I've added that in. Tested: FreeBSD 4.1.1 (hawkwind)
* [svn-r2600] Purpose:Quincey Koziol2000-09-261-1/+9
| | | | | | | | | | | Implemented new feature Description: Added data sieve buffering code to raw I/O data path. This is enabled for all the VFL drivers except the mpio & core drivers. Also added two new API functions to control the sieve buffer size: H5Pset_sieve_buf_size() and H5Pget_sieve_buf_size(). Platforms tested: Solaris 2.6 (i.e. baldric)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./configure.in ./src/H5config.h.in [REGENERATED] The /usr/ncsa/{include,lib} directories are only added if they actually exist. This fixes a warning on some systems. Checks for the <pdb.h> header file and also for either the PDB or Silo library, and if found prepares to compile the pdb2hdf program. ./config/distdep Relative path names for include files are changed to base names since the makefile contains the logic for searching and since it's likely that building the .distdep files happed from a location other than where they would be used in the file system. ./config/conclude.in Fixed shell errors when `for' loops iterate over nothing for the `uninstall' target. ./src/H5D.c ./src/H5Oefl.c File names for the external files are added to the heap when the dataset is created instead of when the object header is written. This fixes a rare infinite recursion bug. ./src/H5FD.c ./src/H5FDpublic.h Optimization to the free list causes H5FD_alloc() usage to go from >10 seconds to <0.4 second for one example (converting a 30MB equation of state file from PDB to HDF5 format). The optimization is to simply keep track of the largest item in the free list and not search the free list when the largest item is not big enough to satisfy the request. ./src/H5FDcore.c ./src/H5FDcore.h ./test/h5test.c If the `backing_store' property is true then a flush causes the entire contents of memory to be written to the specified file. This is in preparation for the ASCI/red optimizations and is currently tested by the pdb2hdf `--cached' switch. ./src/H5Odtypes.c Wrapped three long lines. ./tools/Makefile.in ./tools/pdb2hdf.c [NEW] A PDB-to-HDF5 translator. It only translates meta data -- the resulting HDF5 points into the PDB file for the raw data.

Also added the API tracing call. ./src/H5F.c Added file opening optimizations. If the driver doesn't support the ability to determine when two file handles refer to the same file (like MPIO and GASS) then H5F_open() makes fewer calls to the driver's open callback. Also, if the tentative file access flags are the same as the original flags then H5F_open() makes fewer calls to the file device. ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h Added H5FD_get_class() so the library can get information about what file driver callbacks are defined. This will be useful when more optimization functions are added to the VFL, such as for MPIO derived datatype I/O. ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDmulti.c ./src/H5FDsec2.c The driver symbols (like H5FD_CORE, etc) are actually function calls. The functions were fixed to return correct values even after calling H5close(). ./src/H5FDmulti.c ./src/H5FDmulti.h Added support for opening a file when parts are missing (only if the caller explicitly allows that in the file access property list). Moved some common code sequences into macros or functions. Added better support for reopening files. All the application has to know is that the file is a multi file and the base name from which all the member names are created. More debugging output when the file is opened with the H5F_ACC_DEBUG flag. Fixed various bugs. ./src/H5Fistore.c Chunked raw data was accidently allocated as meta data instead of raw data. ./src/H5I.c The H5Iget_type() function fails when invoked with an old object ID (an ID which has been closed down). ./test/h5test.c Added an extra argument when setting the multi file access property lists so the test fails if it can't open one of the sub-files. ./tools/h5ls.c Improved the algorithm for deciding what file driver to use. It basically tries all of the predefined drivers and is now able to open family, split, and multi files without looking for special characters in the file name. Added `-e' and `--errors' switches which cause errors from libhdf5 to be reported on stderr in addition to the simple error message displayed by h5ls.

The H5Pset_fapl_split() function just calls H5Pset_fapl_multi() with arguments which prepare to split the address space into two files: meta and raw data. This is the first version. I plan to allow the open() call to relax a bit which would allow one to open an hdf5 file when only the meta-data file is present. This would allow a very large file to be split and stored on tape and the relatively small meta file to be mirrored on disk to allow limited browsing of the file (any request for raw data would fail). ./src/H5private.h ./src/H5F.c ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c Added the ability for a file driver to store information in the superblock which would be needed if the file were opened again later for reading. The format is driver-defined which allows users to extend it however they like. ./doc/html/H5.format.html Added information about the new driver information block of the superblock. This is where file drivers store information they need in order to reopen the file later. ./src/H5F.c ./src/H5Fprivate.h ./src/H5FD.c ./src/H5FDprivate.h ./src/H5FDpublic.h ./src/H5FDcore.c ./src/H5FDfamily.c ./src/H5FDmpio.c ./src/H5FDsec2.c ./src/H5Fistore.c ./src/H5R.c The file access properties and the file access property list were decoupled, which allows the property list to more cleanly contain properties for various levels of the file and which allows the property list to be modified more cleanly when opening files. ./src/H5.c ./src/H5FDpublic.h Removed H5FD_MEM_META and H5FD_MEM_GROUP since they're never used. ./src/H5D.c Changed the way we detect the MPIO driver in all these special cases. ./src/H5F.c ./src/H5Rpublic.h ./test/tfile.c The default file sizeof(offset) was changed to be a function of haddr_t instead of hsize_t. THE H5RPUBLIC.H DEFINITIONS WILL HAVE PROBLEMS IF THE USER CREATES A FILE WITH NON-DEFAULT OFFSET AND SIZE SIZES! ./src/H5F.c Fixed an uninitialized memory access bug in file closing related to the VFL. ./src/H5T.c ./src/H5Tpublic.h Added an H5T_NATIVE_HADDR predefined datatype which corresponds to the `haddr_t' type. ./test/Makefile.in Reformatted long lines. ./test/big.c ./test/cmpd_dset.c ./test/dsets.c ./test/dtypes.c ./test/extend.c ./test/external.c Removed the H5F_ACC_DEBUG flag from file creation/open calls. ./test/big.c Plugged a memory leak. ./test/h5test.c Added support for the `multi' driver. Removed #warning about not having the stdio driver. Plans are to not implement it since the sec2 driver serves the same purpose and testing didn't show any difference in execution times between the two.

---------------------- This extensive change is the virtual file layer implementation. I've ported and tested the sec2, family, and core drivers and only ported the mpio driver (Albert will test it). So if you need MPIO I would recommend sticking with the previous version for a while. You will get a few compile warnings about split and stdio drivers not being implemented and possibly tracing information not inserted in some of the drivers. You can safely ignore them but I plan to fix them. I'm still working on the split driver because I just realized that it needs a part of the VFL that isn't written yet. Documentation is being updated also because there were some minor changes (mostly just name changes). It should be available on my web site later this week. ./MANIFEST ./src/Makefile.in ./src/hdf5.h ./src/H5Flow.c [REMOVED] ./src/H5Fstdio.c [REMOVED] ./src/H5Fsec2.c [REMOVED] ./src/H5Fsplit.c [REMOVED] ./src/H5Fmpio.c [REMOVED] ./src/H5Ffamily.c [REMOVED] ./src/H5Fcore.c [REMOVED] ./src/H5MFpublic.h [REMOVED] ./src/H5FD.c [NEW] ./src/H5FDcore.c [NEW] ./src/H5FDcore.h [NEW] ./src/H5FDfamily.c [NEW] ./src/H5FDfamily.h [NEW] ./src/H5FDmpio.c [NEW] ./src/H5FDmpio.h [NEW] ./src/H5FDprivate.h [NEW] ./src/H5FDpublic.h [NEW] ./src/H5FDsec2.c [NEW] ./src/H5FDsec2.h [NEW] Removed/added files for virtual file layer. ./bin/trace ./src/H5.c Removed unused public datatypes and added new VFL public datatypes. Changed an error message. ./config/BlankForm ./config/dec-flags ./config/gnu-flags ./config/hpux10.20 ./config/hpux9.03 ./config/irix5.x ./config/irix6.x ./config/solaris2.x ./config/unicosmk Removed the H5F_OPT_SEEK and H5F_LOW_DFLT constants from the configuration since they're no longer applicable. The default file driver is always the sec2 driver and it always optimizes calls to lseek() or lseek64(). ./config/depend.in C preprocessor errors generated during automatic dependency building are sent to /dev/null to prevent them from appearing twice in the make output. ./src/H5AC.c ./src/H5B.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5Gent.c ./src/H5Gnode.c ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5Oattr.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Oshared.c ./src/H5T.c ./src/H5detect.c ./test/ohdr.c Changed H5F_ADDR_UNDEF to HADDR_UNDEF to be more consistent with the `haddr_t' datatype which is now a public type. ./src/H5D.c ./src/H5P.c ./src/H5Ppublic.h ./src/H5Tconv.c ./test/cmpd_dset.c ./test/dsets.c ./test/overhead.c ./test/tselect.c ./test/tvltypes.c The H5P_DATASET_XFER constant was changed to H5P_DATA_XFER because the properties apply to all types of I/O operations, not just datasets. ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5Dpublic.h ./src/H5F.c ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5HG.c ./src/H5HL.c ./src/H5O.c ./src/H5R.c ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Smpio.c ./src/H5Spoint.c ./src/H5Sprivate.h ./test/big.c ./test/h5test.c ./test/istore.c ./testpar/t_dset.c ./testpar/t_file.c ./tools/h5debug.c ./tools/h5ls.c Modified to work with the virtual file layer by calling H5FD_* functions instead of H5F_low_* functions and by passing file access and data transfer properties by object ID instead of pointer. Changed H5D_transfer_t to H5FD_mpio_xfer_t since the COLLECTIVE vs. INDEPENDENT transfer mode is specific to the MPIO file driver. Moved MPIO-specific stuff into the MPIO driver. ./src/H5B.c ./src/H5D.c ./src/H5Fprivate.h The H5F_mpio_* private functions were renamed and placed in the H5FDmpio driver except those which appeared in H5Smpio.c. ./src/H5E.c ./src/H5Epublic.h Added major error number H5E_VFL for virtual file layer related errors. ./src/H5F.c ./src/H5Fprivate.h Changed the logic that controls whether the boot block is written. Instead of assuming that the first call to write the boot block is only to allocate space, I've added a function argument which makes this explicit. Changed the way files are compared so that a driver-defined comparison function can be called. Files which belong to different drivers are always considered different. Removed H5F_driver_t since file drivers are now identified by object ID instead of a special non-user-extendible datatype. Removed all the hard-coded low-level file properties which have been replaced by the various file drivers. ./src/H5I.c ./src/H5Iprivate.h Added the H5I_inc_ref() which was removed a few months ago since we finally have a use for it. ./src/H5Ipublic.h Added the H5I_VFL object ID type to identify file drivers in the virtual file layer. ./src/H5MF.c ./src/H5MFprivate.h Moved all the allocation/deallocation code into the virtual file layer which allows file drivers to override much of it. ./src/H5P.c ./src/H5Ppublic.h Moved file driver-specific code into the various file driver files. The H5Pcopy() and H5Pclose() functions make calls into the virtual file driver to manage the memory for driver-specific file access and data transfer properties. ./src/H5private.h ./src/H5public.h The `haddr_t' type is now public. ./test/tfile.c Added a few more comments.
